Water Soluble Dietary Fiber

Water-soluble dietary fiber is a type of fiber that dissolves in water to form a gel-like substance. It is often derived from plant sources like grains, fruits, and vegetables. Processing may be used to isolate or modify the fiber for specific applications.

Manufacturers add water-soluble dietary fiber to foods to increase their fiber content, which can improve texture and mouthfeel. It is often used in baked goods, beverages, and dietary supplements. It can also act as a bulking agent or a fat replacer.

Water-soluble dietary fiber is generally recognized as safe (GRAS) by the FDA when used as intended. It is a component of a healthy diet, and adequate intake is associated with benefits like improved digestive health. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) and the European Food Safety Authority (EFSA) have evaluated various types of dietary fibers. Evidence suggests that soluble fiber may help manage blood sugar and cholesterol levels, but more research is ongoing.
